a corporation of Illinois Application December 31, 1937, Serial No. 182,851 s claims. (ci. sa-o) This invention relates to tubed cake pans wherein there is a tube coacting with a central aperture in the bottom of the pan and extending upwardly through the pan to create a center hole or aperture in the products baked th rein, and

particularly to a pan of this type wherein the sides of the pan are upwardly and outwardly and the tube has upwardly converging sides.

It is an object of this invention to provide a pan of this construction having means through which the entering portionthereof may be suspended in spaced nested relation to the internal surface of a similarly constructed subjacent pan.

It is a further object of this invention to provide a pan of this nature having a tube whose upper portion is reinforced.

With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:

Fig. 1 is a fragmentary plan view of a cake pan embodying the features of this invention.

Fig. `2 "is a vertical section of a pair of cake pans constructed as shown in Fig. 1, when in nested relation.

Tubed cake pans are made in various forms and designs. In many instances the pan is made up of ,sides flaring upwardly and outwardly and a tube which has upwardly converging sides, to provide a receptacle adapted to be nested within another pan of similar construction to facilitate packing and storage of a plurality of such pans in a relatively limited amount of space. This formation also caused the mouth or upper end of the pan to be of a larger diameter than the the removal of the pan contents.

40 of these pans in an upright stack, however, the weight of the pans above the bottom pan caused the pans to enter into binding engagement with each other with the result that separation of the pans was made dimcult and at the same time the internal surfaces of the pans became marred or discolored frequently creating a discoloration in the baked product. Binding engagement of the nested pans also prevents proper air circulation between the pans for purposes of uniform cooling.

It is also desirable in pans of this type to have the tube project upwardly beyond the plane of the upper edge of the pan sides, in order that the top of the tube may be used to support the pan and the cake in inverted position prior to release of the baked product and for the purpose of preventing shrinkage in volume during the cooling process-by the action of gravity. In this form of pan, the product is frequently loosened from the pan by pounding the top edge of the tube against a table or other unloading 5 surface, resulting in deforming of the tube.

The diiiiculties encountered in prior pans of this type, as pointed out above, are eliminated by the pan construction forming the subject of this invention, in that the entering portion of the 10 pan may be suspended in spaced relation to the interior of a subjacent pan.

Reference being had more particularly to the drawing, the reference numeral II designates the bottom of a pan of struction, having upwardly and outwardly flaring sides I2 of circular contour terminating in an upper edge I3. Extending upwardly through the pan to create a center hole in the product baked therein and coacting with a central aperture I4 20 in the bottom of the pan is a tube I5 having upwardly converging circular sides I6 terminating in an upper edge I1 above the plane of the edges I3 of the pan sides I2. The edges I3 and I1 of' the pan sides I2 and the tube sides I6, respec- 25 tively, are preferably enlarged to form reinforc-4 ing beads I8 and I9, respectively.

It will be observed that the sides I2 and the sides I6, in connection with the bottom II, form a tapered receptacle which makes it possible to $0 nest the bottom portion of the pan within the upper edges of a subjacent pan of similar con- It will also be noted that' the edges I1 of the tube are so oiset with respect to the plane of the 35 edges I3 of the pan sides I2 as to provide a support through which the pan and the contents may be sustained in inverted relation prior to release of the contents of the pan.

In providing means through which the enter- 40 ing portion af the pan may be suspended in spaced relation to the interior of a similarly formed subjacent pan, it is preferable to employ a device which is removed from the surface of the pan normally. contacting with the product 45 baked therein. To this end, the internal surface of the tube I5 is provided with a series of circumferentially spaced ribs 2li which extend downwardly from the undersurface of the bead I9 at the upper edge of the tube and terminate in 50 a shoulder 2| at their lower ends. The surface of the shoulder 2| is preferably shaped to conform with the upper contour of the bead I9 whereby the bead I9 of a subjacent pan may have snug and engagement therewith. As shown 56 in Fig. 2, engagement of the bead I3 of a subjacent pan with the shoulder 2| of the nested pan bottom and sides of the It will be observed. that the ribs 20, in backing of the bead I9, provides a of that region of the tube engageable by the upper edge of the tube of a subjacent pan in advance of tight nesting of the pans.

3. A cake pan having a central tube and side walls to provide a receptacle adapted to be nested within a pan of similar construction, said tube having a thickened upper portion extending in odset relation to the internal surface of the tube.

l4. A cake pan having a central tube and side surface of the tube having an oiset portion conforming with the contour of the upper edge of the tube.
